ABSTRACT:
The invention relates to a method for carrying out the allocation of the wheel position to tire pressure control devices (6a to 6d) in a tire pressure control system of a motor vehicle. The tire pressure control devices (6a to 6d) transmit their individual identifiers to the central unit (10) of the tire pressure control system at pregiven time intervals. The individual identifiers are transmitted at transmitting time points. At these time points, the wheel assumes a defined angular position so that a defined angular offset is present between two transmission time points. The rotation signals, which are supplied by the rpm sensors (4a to 4d), are checked in the central unit (10) as to which rotation signal exhibits the same angular offset. In the central unit (10), the tire pressure control devices (6a to 6d) are allocated to that wheel position whose rpm sensor (4a to 4d) likewise has measured the pregiven angular offset.
